Super Smooth Calcium Fluoride Prism Manufacturer and Supplier
Trusted by aerospace and defense leaders, our Super Smooth Calcium Fluoride Prism delivers unmatched performance in high-stakes applications. Engineered with 99.99% pure CaF₂ crystals and sub-nanometer surface smoothness (Ra <0.5 nm), these prisms minimize light scattering while withstanding temperatures from -200°C to +400°C. Ideal for laser guidance, satellite optics, and UAV surveillance, they’re built to endure rapid thermal shifts, mechanical shock, and decades of harsh-environment operation.
Why Choose Our Calcium Fluoride Prisms?
- Extreme Temperature Resilience: Maintain optical integrity during rapid thermal cycling (-200°C to +400°C) with a CTE ≤16 x 10⁻⁶/°C, ensuring stability in aerospace re-entry vehicles and industrial furnaces where sudden temperature shifts would warp lesser optics, preserving beam alignment critical for mission success.
- Laser-Grade Surface Quality: Achieve <λ/10 surface accuracy at 633nm for precision targeting and beam collimation, minimizing wavefront distortion in directed-energy systems and laser rangefinders, ensuring pinpoint accuracy that directly enhances operational effectiveness in defense and surveying applications.
- Military-Grade Durability: MIL-STD-810H certified for shock/vibration resistance in hypersonic or armored vehicle systems, withstanding extreme mechanical stress that would damage standard components, guaranteeing reliable performance in combat zones or high-speed aerospace missions where failure is not an option.
- Customizable Designs: Tailor wedge angles (3’–3” accuracy), AR coatings, or non-standard geometries (e.g., pentagonal), adapting to unique optical setups like periscopes or specialized sensors, ensuring seamless integration into proprietary systems without compromising performance or fit.
- Global Compliance: ITAR-controlled, DFARS-compliant, and RoHS/REACH-certified for seamless integration, meeting international defense and environmental standards, facilitating global supply chain adoption in military, aerospace, and commercial sectors with strict regulatory requirements.
